HARRY T. KRAKAU, OF CLEVELAND, OHIO, ASSIGNOR TO THE NATIONAL MALLEABLE CASTINGS COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

COUPLING.

Specification of Letters Patent.

Application filed June 24, 1909. Serial No. 504,050.

To all whom "it may concern:

Be it known that I, HARRY T. KRAKAU, of Cleveland, Cuyahoga county, Ohio, have invented a new and useful Improvement in Couplers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 shows in plan View a coupler constructed in accordance with my invention; Fig. 2 is a side elevation partly in' vertical section of the shank; and Fig. 3 is a rear end view of the shank.

As shown in the drawings, the couplerhead has on its top surface an upwardly projecting lug 1 extending upwardly above the buffer-horn 5 and having lateral bearing surfaces, and adapted to en age a slot or recess in the bottom of a buffer, so that when the coupler and buffer are mounted for radial movement the coupler shank and buffer-shank will be maintained in alinement during their lateral movements.

The coupler shank has at its rear end a vertically extending enlargement 2, provided with transverse holes 3 through which are passed the bolts by which the coupler shank can be attached to a rearwardly extending member or shank extension. The

enlargement of the rear end of the coupler shank enables these holes to be spaced apart and to afford a very strong connection for the shank.

At the middle portion of the couplershank, I form holes 4 which are employed for the attachment of a wearing shoe to prevent wear upon the shank.

I claim:

1. A car coupler having a shank whose rear end portion is enlarged upwardly and downwardly, the enlarged portions being provided with horizontal bolt holes outside the lines of the forward portion of the shank; substantially as described.

2. Acar coupler havinga shank whose rear portion is provided with a vertically extending enlargement 2 provided with horizontal bolt holes 3 outside the lines of the forward portion of the coupler shank, the intermediate portion of said shank having horizontal holes 4 for attachment of a wearing shoe; substantially as described.

In testimony whereof, I have hereunto set my hand.
